EDGAR A STANLEY, or BREWER, MAINE, ASSIG'NOR TO'HIMSELF AN ORLANDO A; PALMER, or SAME PLACE.

Letters Patent No. 102,876, dated May 10, 1870.

The Schedule referred to in these Letters Patent and making part or the same To all when: it may concern Be it known that I, Enenn A.. STANLEY, of Brewer, in the county of -.Penobscot and Stateof Maine, have, invented l certain Improvements in Axle-Nuts; and I do declare that the following is a full and exact description thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon.

The nature of my invention consists .iuso coustruoting the nutgwhich secures the wheel on the axle, as to enable it to be exteudedat pleasure, and exactly graduated, so as to "compensate foo the wear on thecnd of theboxes.

In the accompanying drawings-t, Figure 1 is a perspective viewof the end of a carriage-axle, with the nut removed, showing the end of the box worn away at h, and the journal projecting beyondthe box at a.

Figure 2' is a perspective view of the axle, with the box and nut in place, andmhowing the nut so extended against the box as tohold it still in its proper position.

Figure 3 is a perspective view of the part-of the nutwlnch acts as an extension, showing the screw thread at f, which runs in the thread out on the principal part of the nut G, and by which it is possible to produce the extension of the whole nut at will.

Figure 4 is alougitudinal sectional view of the axle A, .box B, journal D, and nut O C.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its con struction and operation. I p

I construct the axle A, and turn on the end of it the journal D, and provide the box B, all of which may be the same as in general use.

I construct the compound not 0 O in two parts, the part 0 having a female screw, which fits onto the male screw 1), as seen at '0.

I then turn down" the part 0, and 'cut an outside thread or male-screw, g, which fits the female screw fin the part of thennt marked 0', and enables the part 0" to be moved to any desired distance forward or backward on the part I construct the part Q with a flangc, 1'., andprovide a set-screw, d.

This set-screw is arranged to play in the part 0, and, by pressing upon the thread ofthe male screw-g, to hold the part 0' at any desired point on the part 0. i I

In this manner the part 0 may be screwed up and folllow the box 13, as it wears away, and leaves .a space at t.

When the part 0' is set up to the, box, and the set-screw brought to bear ppon the. thread the whole operates as one nut, and is handled and moved as an ordinary nut. In operation this not possesses several' 'great ad vantages:

First, by care in, keeping the part i O screwed up;

to bear against thebox, the wheels may be run ale wheeis run easy, while, in reality, it simply indicates that they are hung about right on the axle or journalj and do 'n o't hug; against-either nut or shoulder;

but when there is play there is concussion, and

this, added to friction, wears awayv the ends. of the bOX' much faster than they would wear with the friction alone.

Third, this nut saves much of thy. wear occasioned by grit and dust, because, being continually "set up against the box, there cannot so much nor get in to grind out the box,

such coarse grit and dust the nut, and the journal.

Fourth, it saves all concu'ssive strain on the wheels, for, when there is the least play, vthe strain of the load commences with a sudden jar or concussion, which strains the wheel, and which is reduced to a steady strain bythe use of ,this nut.

7 Fifth, the original cost of this nut is much less than thecost of the necessary repairs and patching upof the ordinary nut now in common use. As

soon as the boxes begin to wear, it is fonnd necessaryto fill the space between the ordinary nut and the boxes, either with leather, or, in many cases,

iron ririgs are riveted onto the face of the nut. expen'se'and trouble of either operation is more than The thecos't of the extension nut, and one or the-other of these operations must be resorted to before the vehicle'is half worn out. This cannot be remedied with the ordinary nut, as it must be, made to screw upagain'st the shoulder of the journal at a, and the shoulder cannot be left shorter'thau the box, because, in the first place, the moment the nut became dry, it would have a tendency to screw upa'gainst= thebox and bind; and, in the second place, the shoulder of the journal would wear into the box, and

cause serious trouble in the running.

Sixth, this nut economizes the use-ofoil or anything used as a lubricator, because oil will not waste as rapidly when the nut is kept up against the box as when there is an open space at each end.

What I claim as my invention, and wish to secure iby'Le'tters Patent, is-

1. The combination of the outside part 0', inside nut or part 0, and set-screw-d, to form a compound or extension nut.

2. The combination of the .nut or part 0, inside nut or part 0, set-screw d, and axle-screw b the two parts 0 and 0' operating together by means of the male screw 9 and the female screw j, substantially asand for the purpose hereinbcfore set forth. EDGAR A. STANLEY.
